*lualine.txt* fast and easy to configure statusline plugin for neovim ============================================================================== Table of Contents *lualine-table-of-contents* 1. lualine.nvim |lualine-lualine.nvim| - Contributing |lualine-contributing| - Performance compared to other plugins|lualine-performance-compared-to-other-plugins| - Installation |lualine-installation| - Usage and customization |lualine-usage-and-customization| ============================================================================== 1. lualine.nvim *lualine-lualine.nvim* A blazing fast and easy to configure Neovim statusline written in Lua. `lualine.nvim` requires Neovim >= 0.5. CONTRIBUTING *lualine-contributing* Feel free to create an issue/PR if you want to see anything else implemented. If you have some question or need help with configuration, start a discussion . Please read CONTRIBUTING.md <./CONTRIBUTING.md> before opening a PR. You can also help with documentation in the wiki . PERFORMANCE COMPARED TO OTHER PLUGINS*lualine-performance-compared-to-other-plugins* Unlike other statusline plugins, lualine loads only the components you specify, and nothing else. Startup time performance measured with an amazing plugin dstein64/vim-startuptime Times are measured with a clean `init.vim` with only `vim-startuptime`, `vim-plug` and given statusline plugin installed. In control just `vim-startuptime` and`vim-plug` is installed. And measured time is complete startuptime of vim not time spent on specific plugin. These numbers are the average of 20 runs. │control│lualine│lightline│airline│ │17.2 ms│24.8 ms│ 25.5 ms │79.9 ms│ Last Updated On: 18-04-2022 INSTALLATION *lualine-installation* VIM-PLUG ~ > Plug 'nvim-lualine/lualine.nvim' " If you want to have icons in your statusline choose one of these Plug 'kyazdani42/nvim-web-devicons' < PACKER.NVIM ~ > use { 'nvim-lualine/lualine.nvim', requires = { 'kyazdani42/nvim-web-devicons', opt = true } } < You’ll also need to have a patched font if you want icons. USAGE AND CUSTOMIZATION *lualine-usage-and-customization* Lualine has sections as shown below. > +-------------------------------------------------+ | A | B | C X | Y | Z | +-------------------------------------------------+ < Each sections holds its components e.g. Vim’s current mode. CONFIGURING LUALINE IN INIT.VIM ~ All the examples below are in lua. You can use the same examples in `.vim` files by wrapping them in lua heredoc like this: > lua << END require('lualine').setup() END < For more information, check out `:help lua-heredoc`. *lualine-Default-configuration* > require('lualine').setup { options = { icons_enabled = true, theme = 'auto', component_separators = { left = '', right = ''}, section_separators = { left = '', right = ''}, disabled_filetypes = {}, always_divide_middle = true, globalstatus = false, }, sections = { lualine_a = {'mode'}, lualine_b = {'branch', 'diff', 'diagnostics'}, lualine_c = {'filename'}, lualine_x = {'encoding', 'fileformat', 'filetype'}, lualine_y = {'progress'}, lualine_z = {'location'} }, inactive_sections = { lualine_a = {}, lualine_b = {}, lualine_c = {'filename'}, lualine_x = {'location'}, lualine_y = {}, lualine_z = {} }, tabline = {}, extensions = {} } < Default configuration If you want to get your current lualine config, you can do so with: > require('lualine').get_config() < ------------------------------------------------------------------------------ STARTING LUALINE ~ > require('lualine').setup() < ------------------------------------------------------------------------------ SETTING A THEME ~ > options = { theme = 'gruvbox' } < All available themes are listed in THEMES.md <./THEMES.md>.

See `:h lua-vim-variables` and `:h lua-vim-options` if you are not sure what to use. > sections = { lualine_a = { 'g:coc_status', 'bo:filetype' } } < LUA EXPRESSIONS AS LUALINE COMPONENT You can use any valid lua expression as a component including: - oneliners - global variables - require statements > sections = { lualine_c = { "os.date('%a')", 'data', "require'lsp-status'.status()" } } < `data` is a global variable in this example. ------------------------------------------------------------------------------ COMPONENT OPTIONS ~ Component options can change the way a component behave. There are two kinds of options: - global options affecting all components - local options affecting specific Global options can be used as local options (can be applied to specific components) but you cannot use local options as global. Global option used locally overwrites the global, for example: > require('lualine').setup { options = { fmt = string.lower }, sections = { lualine_a = { { 'mode', fmt = function(str) return str:sub(1,1) end } }, lualine_b = {'branch'} } } < `mode` will be formatted with the passed function so only first char will be shown. On the other hand branch will be formatted with global formatter `string.lower` so it will be showed in lower case. *lualine-Available-options* *lualine-Global-options* Global options These are `options` that are used in options table. They set behavior of lualine. Values set here are treated as default for other options that work in component level. For example even though `icons_enabled` is a general component option. you can set `icons_enabled` to `false` and icons will be disabled on all component. You can still overwrite defaults set in option table by specifying the option value in component. > options = { theme = 'auto', -- lualine theme component_separators = { left = '', right = '' }, section_separators = { left = '', right = '' }, disabled_filetypes = {}, -- Filetypes to disable lualine for. always_divide_middle = true, -- When set to true, left sections i.e. 'a','b' and 'c' -- can't take over the entire statusline even -- if neither of 'x', 'y' or 'z' are present. globalstatus = false, -- enable global statusline (have a single statusline -- at bottom of neovim instead of one for every window). -- This feature is only available in neovim 0.7 and higher. } < *lualine-General-component-options* General component options These are options that control behavior at component level and are available for all components. > sections = { lualine_a = { { 'mode', icons_enabled = true, -- Enables the display of icons alongside the component. -- Defines the icon to be displayed in front of the component. -- Can be string|table -- As table it must contain the icon as first entry and can use -- color option to custom color the icon. Example: -- {'branch', icon = ''} / {'branch', icon = {'', color={fg='green'}}} -- icon position can also be set to the right side from table. Example: -- {'branch', icon = {'', align='right', color={fg='green'}}} icon = nil, separator = nil, -- Determines what separator to use for the component. -- Note: -- When a string is provided it's treated as component_separator. -- When a table is provided it's treated as section_separator. -- Passing an empty string disables the separator. -- -- These options can be used to set colored separators -- around a component. -- -- The options need to be set as such: -- separator = { left = '', right = ''} -- -- Where left will be placed on left side of component, -- and right will be placed on its right. -- cond = nil, -- Condition function, the component is loaded when the function returns `true`. -- Defines a custom color for the component: -- -- 'highlight_group_name' | { fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style' } | function -- Note: -- '|' is synonymous with 'or', meaning a different acceptable format for that placeholder. -- color function has to return one of other color types ('highlight_group_name' | { fg = '#rrggbb'|cterm_value(0-255)|'color_name(red)', bg= '#rrggbb', gui='style' }) -- color functions can be used to have different colors based on state as shown below. -- -- Examples: -- color = { fg = '#ffaa88', bg = 'grey', gui='italic,bold' }, -- color = { fg = 204 } -- When fg/bg are omitted, they default to the your theme's fg/bg. -- color = 'WarningMsg' -- Highlight groups can also be used. -- color = function(section) -- return { fg = vim.bo.modified and '#aa3355' or '#33aa88' } -- end, color = nil, -- The default is your theme's color for that section and mode. -- Specify what type a component is, if omitted, lualine will guess it for you. -- -- Available types are: -- [format: type_name(example)], mod(branch/filename), -- stl(%f/%m), var(g:coc_status/bo:modifiable), -- lua_expr(lua expressions), vim_fun(viml function name) -- -- Note: -- lua_expr is short for lua-expression and vim_fun is short for vim-function. type = nil, padding = 1, -- Adds padding to the left and right of components. -- Padding can be specified to left or right independently, e.g.: -- padding = { left = left_padding, right = right_padding } fmt = nil, -- Format function, formats the component's output. } } } < *lualine-Component-specific-options* Component specific options These are options that are available on specific components.
